In occupations that work in areas where exhaust levels are high or can accumulate, such as police and traffic officers, custom officer/border control booths, ticket/toll booth operators, drivers of diesel vehicles (buses, subway/railway, truck, taxi, forklift, etc.), airline ground crew, farm workers, vehicle maintenance workers, dock/cargo/passenger ship workers, miners, tunnel construction workers, landscapers, etc.Where diesel exhaust can accumulate, such as warehouses, car/bus depots, ferries/ships, garages, vehicle testing sites, fire stations, mines, or where diesel generators or winch motors are used.In areas where diesel powered vehicles are used repaired, or tested such as forklift trucks, railway locomotive, buses, trucks, construction vehicles, farm vehicles.The fine and ultra fine particles are respirable, which means that the particles can avoid many of the human respiratory system defense mechanisms and enter deeply into the lung. The most common way individuals are exposed is by breathing air that contains the diesel particulate matter. Who is at risk of exposure to diesel exhaust? Back to top The International Agency for Research on Cancer (IARC), which is part of the World Health Organization (WHO), classified diesel engine exhaust as carcinogenic to humans (Group 1), determining that exposure to diesel exhaust emissions increases the risk for lung cancer and possibly bladder cancer. Long term exposure may lead to serious health effects. Other symptoms may include feeling lightheaded, headache, or nausea. Breathing in diesel exhaust can cause lung irritation and/or an allergic reaction causing asthma (wheezing and difficult breathing), or making pre-existing asthma worse. Short term exposure to diesel exhaust can cause coughing, and irritation of the eyes, nose, throat, and respiratory tract. What are the main health concerns? Back to top Almost all particulate emitted by diesel engines is respirable (PM <10 micron), with the majority of the particulates have diameters less than 1.0 micron. Aromatic compounds such as benzene, toluene, and polycyclic aromatic hydrocarbons (PAHs)ĭiesel particulate matter (DPM) is primarily made up of soot particles, carbon, ash, polycyclic aromatic hydrocarbons (PAHs), metallic abrasion particles, sulfates, and silicates.Oxides of sulphur (e.g., sulphur dioxide).Oxides of nitrogen (e.g., nitrogen oxide, nitrogen dioxide).The exact nature of the exhaust depends on a number of factors including the type of engine, how well serviced/maintained the engine is, type of fuel, type of oil, speed and load on the engine, and emission control systems. The exhaust is a complex mixture of gases, vapours, aerosols, and particulate substances. Diesel exhaust is produced by the combustion (burning) of diesel fuel.
